III. Comparison with Key Models in the Same Series Table

Model Communication Encoder 2 Security Applicable Scenarios

CSB01.1C-PB-ENS-EN1-NN-...-FW PROFIBUS HSF/RSF Incremental (8V) No Dual incremental feedback, general automation

CSB01.1C-PB-ENS-EN2-NN-...-FW PROFIBUS SSI Absolute Value (5V) No Absolute value full closed-loop, machine tool

CSB01.1C-ET-ENS-EN1-L2-...-FW Multi-Ethernet HSF/RSF Incremental STO SIL3 Safety + Ethernet, automotive / new energy

Four, Key Features

Native support for PROFIBUS: Special for BASIC series, stable and efficient connection with Siemens PLC (S7-300/400/1200/1500)

Dual incremental encoder (ENS + EN1):

Motor end (ENS) + external incremental (EN1) dual-loop feedback, improving positioning stability

Suitable for synchronous shafts, tension control, general machine tools

C-type expandable: With expansion slot, can be later installed with safety module (L1/L2), communication module

Firmware pre-installed FW: Factory authorization, no additional activation required, plug-and-play

No safety cost optimization: NN omits safety circuit cost, suitable for scenarios without safety requirements
